Geofence Integrity Verification Checklist (MSHA/DMR Compliant)

Geofence integrity verification is a critical safety-critical process in autonomous mining operations, where geofences define no-go zones (e.g., pit edges, high-voltage areas, personnel zones) and operational corridors for haul trucks. Regulatory frameworks—particularly MSHA’s Part 46/48 training mandates, Part 56 safety standards for surface mines, and DMR’s digital reporting obligations—require demonstrable assurance that geofences remain operationally sound under dynamic conditions (e.g., GNSS degradation, map version drift, software updates). Verification encompasses multi-layered validation: spatial (coordinate reference system alignment, datum consistency, and sub-meter positional accuracy using RTK-GNSS or PPK surveying), temporal (latency monitoring between geofence state update and vehicle response ≤ 200 ms), and functional (fail-safe behavior testing, including immediate deceleration or stop on geofence violation, with redundant sensing via LiDAR, radar, and inertial navigation). Additionally, the checklist mandates traceable documentation—including geofence metadata (creation timestamp, responsible engineer, CRS EPSG code), version-controlled digital maps, audit logs of all modifications, and evidence of periodic re-verification (minimum quarterly, or after any mine geometry change or AHS software release). Compliance is not static: it requires integration with MSHA’s Accident Prevention Program (APP) and DMR’s real-time telemetry reporting infrastructure to ensure geofence status (active/inactive, degraded/healthy) is logged and reportable.
